Buying a new boiler is not an everyday purchase, therefore to make the right choice and secure the best price we advise you shop around first and compare prices. For instance, get a quote from a reputable national installer and compare it with one from a local boiler installer. Also make certain your engineer is Gas Safe Registered in order to be confident of a safe and professional installation.
